The cross-sectional images of skeletal muscle area at the level of the third lumbar spine was obtained based on computed tomography (CT), and the SMI was calculated by skeletal muscle mass through height squared normalization. Skeletal muscle index and skeletal muscle loss (SML) were obtained ...
The skeletal muscle index, a widely used measure, adjusts for height as (SMA/height2) but uses no BMI adjustment. There is no agreed upon standard for body size adjustment. We extracted L3 SMA using non-contrast-enhanced CT scans from healthy adults, split into ‘Under-40’ and ‘Over-...
The purpose of this investigation was to validate that in vivo measurement of skeletal muscle attenuation (MA) with computed tomography (CT) is associated with muscle content. Single-slice CT scans performed on phantoms of varying concentrations revealed good concordance between attenuation and concentrat...

The diagnosis of sarcopenia is based on the loss of muscle strength and skeletal muscle mass or physical performance2,3,4,9. Grip strength is used as an indicator of muscle strength, and computed tomography (CT), a bioelectrical impedance analysis (BIA), and dual-energy X-ray absorptiometry ...
Psoas muscle areas were measured on CT scans at the third lumbar vertebra. Areas less than the sex-specific median were deemed low skeletal muscle masses (SMMs). Results Low-SMM patients were significantly more often older (p = 0.002) than high-SMM patients, had lower serum albumin (p...
The cross-sectional skeletal muscle area at the level of the third lumbar vertebra using computed tomography was adjusted for patients' height, resulting in the skeletal muscle index. The lowest quartile per sex was defined as LSMM. Short Nutritional Assessment Questionnaire for Residential Care and...
(c) were present from WT and βarr1KO mice after 4 weeks treatment of vehicle or clenbuterol (1 mg/kg/day). Normalized muscle index was presented as a fold increase over vehicle stimulation. Means ± SEM are shown from 7 to 8 mice per group. Statistical comparison was performed by...
Whether adipose tissue and skeletal muscle losses begin before diagnosis and the potential utility of such losses for earlier cancer detection are not well understood. We quantify skeletal muscle and adipose tissue areas from computed tomography (CT) imaging obtained 2 months to 5 years before cancer...
